Title: Construction of ships' hulls
IPC: B63B9/00
Filed: 1967-08-11
Abstract: A method of constructing a ship's hull includes the steps of launching two prefabricated portions H1, H2, Fig. 3, of the hull and effecting permanent connection thereof to each other by, e.g., welding, while they are afloat and temporarily held together by, e.g., external connecting-means (not shown) or bolting internal ribs R1, R2 in one portion to corresponding ribs in the other portion, external connecting- operations on the plates below the waterline L being performed within a caisson 10 that is temporarily placed adjacent said portions in the region of the joint therebetween. The portion H1 may be constructed so that it initially includes the adjacent end section of the portion H2, which section is delimitated by a plane C, this section being severed by, e.g., flame cutting, from the portion H1 before this portion is launched, whereafter the remainder of the portion H2 is constructed such that it is incorporated with said section. This procedure ensures that a satisfactory joint is obtained when the two portions are united in the manner aforesaid. The ribs R1, R2 in said section and the corresponding ones in the portion H1 may be either rendered integral with each other and severed by flame cutting before this portion is launched or provisionally attached to each other by bolts E, Fig. 4, engaging with flanges F on the ribs, which are spaced apart by a packing strip D to provide compensation for loss of material when the plates are cut during severance of the end section, the packing strip being omitted when the two portions are united. Alternatively, the ribs R1, R2 are rendered such that a gap exists between the plates on the adjacent ends of the two portions of the hull when they are brought together, this gap being subsequently bridged by lodging additional plates between said ends and attaching these plates by welding. The hull may comprise more than two prefabricated portions and the method may be employed in effecting enlargement of a hull by insertion of at least one prefabricated portion between the existing portions of the hull. The caisson 10 has the configuration of an open channel and is furnished with upwardlyextending sections at its ends, flanged plates A being provisionally fixed to the sides of each portion of the hull to facilitate sealing of the lateral edges of said sections. Sealing strips 22 are lodged in the edges of the caisson and buoyancy chambers (see Division E1) are formed in the caisson so that it can be conveniently manoeuvred and held against the portions of the hull while water in a working space or gallery 14 is discharged.

Title: Novel cross-linked derivatives of macromolecular anhydro-glucosides
IPC: C08B33/00
Filed: 1968-05-29
Abstract: Polysaccharides composed predominantly of alpha-1,4-glucopyranose units, e.g. starches, amylose or amylopectin, are reacted under alkaline conditions with both a monohalogen fatty acid and a dihalogen fatty acid, or their alkali metal salts, in the presence of water and an organic solvent. Mono- and di-chloroacetic and -propionic acids and their Na salts are specified. The solvent may be acetone, MeOH, EtOH, DMF, toluene, benzene, hexane or, advantageously, dioxolane. The water present may be that inherently present in the polysaccharide. The two acids may be reacted simultaneously or in separate stages. In one example, corn starch is treated with HCl, then with Na mono- and dichloroacetates, followed by HCl. In a modification, an already existing alkali salt of the carboxymethyl ether of the polysaccharide is reacted under the above conditions with the dihalogen acid only. The products are stated to be cross-linked and to contain ester groups.
Patent ES-356191-A1 (ES)
Title: Process and apparatus for producing novelty yarns
IPC: D02G3/34
Filed: 1968-07-16
Abstract: and D1W. In a method of making fancy e.g. looped, undulated or knapped, yarn, core and effect threads are combined by false-twisting with the effect thread overfed e.g. 10-300%, relative to the core and then, before the disappearance of the false-twist, the assembly is bound (optionally, also by false-twisting) with a binding thread applied, optionally with overfeed, at the instant of locking or arresting the false-twist i.e. at the point in the yarn from which twist runs forwards and backwards in opposite direction. The rate of overfeed of the effect thread may be continuously or intermittently variable. The effect thread may be distributed irregularly over the core thread as a result of its oscillation in a direction parallel to the core as it is fed in a direction normal to the direction of advance of the core thread. As shown in Fig. 1, core thread 1 is fed, simultaneously with effect thread 2, into a false-twist device comprising a hollow spindle 3 having a driving whorl 4 surmounted by an uptwister flyer 5 freely rotatable on the spindle head and carrying an eyelet 6 through which binding thread 7, supplied from a bobbin 8 rotating with the spindle, passes with the threads 1, 2, to take-up. In a modification, Fig. 2 (not shown) the effect thread 2 is fed by driven nip rollers (10, 11) normally to the direction of advance of the core thread 1 and is oscillated by a finger (12): the rolls may be rotated at continuously variable speed which may at intervals be abruptly reduced to zero. Irregular and intermittent overfeed may be controlled by a programmer (25) Fig. 3 (not shown) which selects which of two different speed drives is transmitted via a clutch plate (17 or 18) to a counter-plate (16) carried on a spindle mounting driven rolls (14, 15) for advancing an effect thread to the running core thread on the entry side of a falsetwist spindle. A fixed ring carrying a traveller or a double-twist spindle as described in British Specification No. 921205 may be used to combine the threads. As shown in Fig. 4, core thread 1 is withdrawn under high tension from a bobbin 34 and, as it travels through an effect thread 2 which is overfed by controlled rollers 37, 38. The thread assembly travels on to a bar 40 secured to a rotating plate 39 and is associated with a binding thread 7 in a false-twisting device constituted by a hollow tube 41 carrying a thread deflector 42 and guides 43, 44. Binding thread 7 is withdrawn from a bobbin 45 mounted on a fixed bobbin carrier 46 immobilised by magnets 47, 48, and having an axial conduit 49 serving for the passage of thread 7. The composite yarn leaves through the hollow spindle 50 of the tube 41 and is wound on a bobbin 51.

Title: Deflection circuit for regulating the high voltage load
IPC: H04N3/18
Filed: 1968-10-29
Abstract: In a line deflection circuit for a television receiver, the internal resistance Ri of the E.H.T. supply is minimized by selection of the output transformer parameters such that the curren tin the leakage inductance and the differential coefficient of the current are zero at the instants of opening and closure of the primary current whilst the two parallel resonant frequencies exhibited across the primary and the parallel resonant frequency of the leakage inductance and its associated capacitance, lie within specified limits. The ratio of the two primary resonant frequencies is preferably 4À56 (so-called fifth harmonic tuning) whilst the resonant frequency of the leakage inductance is preferably 7À05 times the fundamental resonant frequency. As shown in Fig. 1, the lower part of winding 5 is tightly coupled to the lower part of winding 6 (ratio 1:1), the leakage inductance being further reduced by means of a variable inductor 20 tuned by a capacitor 21. The secondary capacitance may be reduced by use of a transformer (Fig. 4, not shown) having the secondary 6 wound with triangular (or stepped-triangular) cross-section. The resulting flyback pulses 23 (Fig. 6a) have a smooth top conducive to a long conductive period of the E.H.T. rectifier D. A VDR or bleeder resistor 26 may be included in arrangements in which the flyback pulses have two peaks. The booster capacitor 8 is connected between the two parts of the primary winding 5. A focus voltage is available at F. In Fig. 2 (not shown) the pentode 1 is replaced by a transistor, the booster diode 2 is connected across the transistor whilst the deflection coil 7 and capacitor 61 are connected across the primary 5.

Title: Levelling system for vehicle headlamps
IPC: B60Q1/10
Filed: 1968-11-19
Abstract: A levelling system for a vehicle headlamp includes a headlamp (11) mounted about a horizontal axis (12) means for pivoting the lamp according to the attitude of the vehicle body relative to the road and locking means (24) sensitive to the attitude of the ground occupied by the vehicle to prevent adjustment of the headlamp except while the vehicle is on horizontal ground. Lever 13 pivots about 14 to adjust the attitude of the headlamp 11 according to whether the vehicle is loaded at its rear or front. Lever 17 is mounted on a brake drum of the vehicle and when the vehicle is on other than horizontal ground then one of the two pairs of contacts 19, 22 or 21, 23 will be closed and thus energize electromagnetic brake 24 which will prevent weight 15 and lever 13 moving to bring the headlamp 11 back to the horizontal. Dampers 26, 27 are provided to prevent the levers being moved by irregularities in the ground. The system may be modified by arranging that headlamp 11 replaces the lever 13. Further the lever 17 need not be mounted on a brake drum but on some other part of the vehicle which is not moved angularly during loading of the vehicle.

Patent ES-393283-A1 (ES)
Title: Power plant
IPC: F16H47/08
Filed: 1971-07-15
Abstract: A power plant includes an internal combustion engine which drives a planetary differential through a lockable hydrostatic torque converter. One of the differential outputs drives a supercharging air compressor, while the other output drives the power plant load through a drive shaft. The two outputs are inter-connected by a variable displacement hydrostatic drive including a pump and a motor. Thus a split path drive through the hydrostatic leg and through the mechanical connection to the output is provided. A controller receives an engine speed signal, a manifold pressure signal and an engine speed setting and provides an output signal to control a variable fuel supply to the engine and another output signal for controlling adjustment of the hydrostatic pump and motor. A governor is responsive to the speed of the load to control lock-up of the torque converter. In operation at high load speeds, the hydrostatic drive leg is locked out, the compressor is idle, and the torque converter is locked up, yielding an overdrive ratio. Higher power demands caused by increases in power plant load will cause activation of the hydrostatic leg to vary the drive ratio and activate the compressor to increase engine power. Upon further increase of the load, the torque converter unlocks, enabling torque multiplication and maintenance of relatively high engine speed for high power output. The effect of this power plant is to provide reserve power in a usable range only, while maintaining engine speed in an optimum power range.
